Cage nuts and screws are hardware components used in mounting equipment onto racks and cabinets. Cage nuts are square or round nuts with threaded holes and are inserted into square holes on the rack or cabinet rails. The screws are then inserted into the threaded holes in the cage nuts to secure the equipment in place. Threaded screws come in various lengths and diameters to accommodate different equipment and rack or cabinet depths. Thumb screws have a larger, knurled head for easy gripping without the need for a screwdriver, while tool-less screws can be installed and removed by hand without the need for any tools. These components are essential in ensuring a secure and stable installation of equipment on racks and cabinets.
